This article explains the importance of automotive paint. You can determine whether a used car is an accident car from the automotive paint thickness measured with a coating thickness gauge.

Different brands of cars have the same paint finish, but some cars have different paint types, some people use instruments to measure the hardness of the paint. Some people use coating thickness gauges to check the paint thickness. Many people think that car paint is thicker. Because in this case, it is more wear-resistant. Is this really the case?

1. Classification of car paint types

Commercial automotive coatings are generally classified into three categories. They are ordinary paint, metal paint and pearl paint. Ordinary lacquer is the most common one. It is synthesized from resin, additives, pigments and other materials. Metallic paint is made by adding metal powders such as aluminum powder and copper powder to ordinary paint, which looks bright in the sun. Pearlescent paint and metallic paint are not very different. It is based on the addition of mica particles to ordinary paint. The light of different angles will change color and its reflection is better.

2. Thickness measurement of automobile paint in real life

When conducting scientific research on ordinary used cars, it is necessary to know whether there is an accident before the used cars. If the car spray paint has a safety accident again, the paint thickness of a general car measured by a coating thickness gauge will exceed 200 μm. The car paint thickness in all normal processing plants is generally 110 μm to 140 μm. So friends who want to buy a used car recommend a particularly useful tool name here: LS220 coating thickness gauge, it is very easy to use and can quickly measure the thickness of the car paint surface.

In short, it is not that the thicker the paint, the better the quality of the car and the more durable it is. There are four layers of automotive paint in the past, including topcoat electrophoretic architectural coatings, middle architectural coatings, paint layers and topcoat layers. Japanese car paint layers are thinner than ordinary car paint layers, so ordinary people think that the quality of Japanese cars is not good and unsafe, but the thin thickness of car paint has nothing to do with car quality. Nowadays, with the rapid development of scientific and technological progress, automotive coatings do not need to make too many layers and have achieved the same effect as the previous four layers.

3. Hardness of car paint

The hardness index mainly depends on the "varnish coating" in the paint layer, which is the outermost layer. In other words, the previous four-layer paint has now become three layers, which is much thinner than before. But this does not affect the scratch resistance of the car paint. The general hardness of the car paint is H, the harder is 2H. The surface car paint of some high-end models may be harder, even reaching the level of 3H or 4H, which is almost comparable to plating.

So the original car paint thickness has nothing to do with the quality of the car. Today's car technology is more developed, not only the car paint thickness has changed, but many places on the car are also changing. The car paint thickness and whether the car is scratch-resistant have no direct impact. Even the previous four-layer car paint will be scratched when it collides.

Coating thickness gauge LS220, also known as coating thickness meter, is a powerful assistant for buying used cars!
